My'invention relates to improvements in electric portable lamps and hasreference particularly to the construction of a wall lamp or sconce,which is capable of being readily attached and 5 detached from the wall,and which lends itself to an almost endless number of designsappropriate to this type of lighting fixture.

Portable wall lamps have already been devised and used with an extensioncord and plug for 10 connection in the ordinary electric wall socketsand these lamps have found a wide market, because of the fact that onemay avail oneself of the beauty and charm of side wall electric lightfixtures without the necessity of inter-wall wiring l5 installations andthe expense therefor. The present type of fixture has the addedattraction that it is portable and may be made available wherever thereis a wall socket to receive the plug connection.

2 The object of the present invention is to improve upon the known typesof portable wall fixtures by making a bracket of one piece of springymaterial, one arm of which is longer than the other so as to bring thebracket under tension 2 when it is in attached position to hold itfirmly against displacement and to aid in maintaining its proper uprightposition.

A further object of my invention is to provide a slotted aperture in thefixture which will en- 30 able the electric extension cord to take itsproper position without requiring it to be threaded through a series ofopenings with the result that the plug may be attached to the cordbefore assembling the lamp bracket.

35 I accomplish these objects by means of the embodiments of myinvention hereinafter described in the specification, set forth in theappended claims and illustratively exemplified in the accompanyingdrawing, in which 4 Figure 1 is a side elevational view of the portablewall lamp;

Figure 2 is a back view of the same; and

Figure 3 is a perspective 'view of a modified form of bracket.

45 Referring to the drawing and particularly to Figures 1 and 2, II]denotes a side wall to which the wall bracket may be attached and I Ithe push pin or tack which has been placed in the Wall and forms asupport for the bracket.

5 The bracket, designated I2, comprises a substantially V-shaped memberbent from a single strip of springy material, preferably steel, one armI3 being longer than the other arm I4 and both arms having their freeends curved into 55 coils I5 following the same direction. In positionfor use as a bracket the V-shaped member is disposed with one armdirectly above the other, the shorter arm I4 being the uppermost and atright angles to the wall I while the longer arm I3 projects downwardlyat an inclination towards a:

the wall. The normal position of the longer arm I3 when not undertension, i. e., when free of the wall, is substantially that indicatedin dotted lines in Figure 1, but when the free end of arm I4 is broughtinto contact with the wall, the arm I3 springs to the full line positionand is held under tension and in frictional contact with the wall at itsfree end. The curved portion of the coil I5 of the upper and shorter armI4 abutting the wall is provided with an orifice I6 to accommodate thepassage of the head of the pin II therethrough and to allow the head toseat itself against the inner curved surface of the coil and to providea more or less tension hold of the pin upon the bracket. The longer armI3 is provided with an elongated slot I1 extending about the curve inthe coil I5 abutting the wall, the slot I'I allowing the electric cordI8 to pass from the space between the arms I3 and I4 and to a pointbelow the bracket without the necessity of threading it through anyopening in the lower arm.

Any type of electric fixture may be mounted upon the upper arm I4, butfor purposes of illustration I have shown a lamp comprising a ballbottom I9 set in adepression 20 in the midportion of the arm I4, lampsocket 2| mounted upon the ball I9, an incandescent bulb 22 in thesocket and a shade 23 carried by the bulb. The socket ZI is of the typeprovided with a switch and bottom 24. The ball bottom I9 is attached tothe arm I4 by means of a screw connection 25, which allows the cord I8to pass therethrough into the space between the arms I3 and I4, andwhich passes through an opening 26 in the arm to receive a nut 25capable of being screwed over the connection and against the under-faceof the arm to firmly hold the lamp in position. The free end of theextension cord I8 is provided with the usual plug in connection 28mounted in the wall [0 adjacent the floor.

Referring now to Figure 3, the bracket in this embodiment comprises astraight wall portion 29 and an outwardly curved portion projecting fromthe wall in a curved line to form the longer arm I3 the shorter arm: I4being constructed by turning the material at the outer end of arm I3upwardly and then backwardly again upon itself. The free end of theshorter arm I4 is curved in a coil 30 having an orifice 3| toaccommodate the pin H. The outer end of the shorter arm W is providedwith an orifice 32 to receive a lamp fixture 33, the cord l8 projectingdownwardly over the face of the longer arm l3 and being guided to apoint below the bracket in an upright slot 34 in the straight wallportion 29. The lower end of the longer arm 13 is provided with aprojecting arm 35 disposed at right angles to the portion 29 andarranged directly beneath the other arms l3 and M Mounted on the top ofthis arm 35 is a dish or any other receptacle 36 for a flower pot, vaseor the like.

To install the present bracket, the pin II is,

placed in the Wall l at the desired location and the opening l63l in theshorter arm M, M isplaced over the head of the pin which is-then.

allowed to project through the opening. The bracket moves down slightlyuntil the top wall of the opening I6-3l rests upon the stem of the pinand the head engages the material about the opening. When the upper arml4, M is set the latter will be at right angles to the wall I0 and thelonger arm I3, l3 will spring outwardly and downwardly until it is incontact with the wall to hold the bracket in position.

Having now described my invention and the manner in which the same isoperated, what I claim and desire to secure by Letters Patent is:

1. In combination, a bracket of springy material having a pair of arms,one thereof being shorter than the other and adapted to support a lamp,the free end of the longer arm being slotted to accommodate an electriccord from the lamp, and means to attach the free end of the shorter armto a supporting surface,while the longer arm springs away from theshorter arm to bring its free end into frictional contact with thesupporting surface.

. end of the said longer arm, said supporting arm being inclined withrespect to the supporting surface and adapted to support a weight inorderto produce stable suspension of the bracket.
